초록

$Y_2O_2S$:Eu phosphors were synthesized via solid-state reactions. $Y_2O_2S$:Eu phosphor particles of various sizes were obtained by varying the firing temperature and firing time. The photoluminescence properties of these $Y_2O_2S$:Eu phosphors were examined. In addition, the cathodoluminescence properties of the $Y_2O_2S$:Eu phosphors were examined for applied voltages of 3-8 kV. The relationship between the luminescence intensity and particle size of the$Y_2O_2S$:Eu phosphors was investigated. The photoluminescence and cathodoluminescence of the $Y_2O_2S$:Eu phosphors are affected differently by variations in particle size.
